Different factors can cause system errors, including conflicts among device drivers, software, and hardware, and corrupt elements in files. Although a system error occurs only when you work with Adobe Creative Suite 5 or CS5.5, Adobe Creative Suite isn't necessarily the cause. It's possible that it's the only application that uses enough memory or processor cycles to expose the problem.
Read Troubleshoot uninstallation issues | Adobe Creative Suite 5 and CS5.5 products before you attempt the solutions in this document. Then, perform the tasks in order. Record the tasks you perform and the results of each, including errors or problematic behavior. Adobe Technical Support can use this information to assist you if you call.
Important: Back up all personal files before performing any of these tasks. Always restart the computer after a system error occurs to refresh its memory. Continuing to work without restarting the computer can compound the problem.
